To all wtmn it may concern:

Be it known that I, AUSTIN FRYERs, journalist, asubject of the King ofGreat Britain and Ireland, residing at Kirk-Lynton, Sydenham Hill Road,Sydenham, in the county of Kent, England, have invented certain new anduseful Improvements in Pivotal Stages or Turn-Tables, of which thefollowing is a specification.

This invention relates to a pivotal stage or turn-table, having for itsobject to provide a revolving motion to any person or object standingthereon, and is espeeiallyapplicable for the use of actors or forproducing theatrical or other effects. The said turn-table or platformwhen used for theatrical purposes is placed in one of the stage-traps,the upper surface of the platform being level with the stage and forminga partfof the same.

The accompanying drawing illustrates a method of carrying out myinvention when applied to stage purposes, the view showing a sectionalelevation of the apparatus.

a is a Wooden (or it may be a metal) case or box, with an opening in.the top containing the apparatus, and b is a bed or base of metal o1'other material for supporting the mechanism.

c is a conical recess formed in the center of the bed and fitted with asteel screw d, provided With-a coned bearing to receive a ball e, actingas a pivotal support to the platform. The screw CZ is adjusted and xedby the nut f, held in the recess g, to permit of its beingv turned.

h is the platform or turn-table, and a steel This shaft is held in avertical position by means of a bridgepiece j, fixed to the base b andprovided with a ball-race 7c, of hardened steel, forming, with the coneZ, screwed on the shaft, and balls on, an antifriction-bearing for'theshaft in addition to the lower bearing.

n is a balance or Iiy wheel fitted tol the shaft 'and having adjustableballs n for maintaining the revolving impetus given to the platformeither bythe performer thereon or by another operator. The shaft may bealso fitted with a pulley o, whereby it can be operated by means of acord p from any convenient place underneath the stage.

The platform is made of Wood, metal, or any suitable material and islevel'with the top of the case a, which latter may be placed in one ofthe stage-traps, its upper surface being likewiselevel with the stage r.

The invention is especially applicable for the use of dancers requiringto exhibit and maintain revolving motions on a vertical axis;

`but`it is'likewise applicable to other requirements or cases in which apivotal revolving `fixed to the shaft for operating the same, and

an open-top boX or case containing the appa- `ratus, substantially asdescribed.

In Witness whereof I have hereunto set my hand in the-presence of twowitnesses.
